    摘要: A hearing aid module is shaped for insertion into a tunnel made through the soft tissue that connects the retro-auricular space with the ear canal. The hearing aid module contains a speaker or auditory transducer, a battery or other power source powering the module, signal processing circuitry, a microphone, and a hollow tube which contains a steroid or drug. Telemetry circuitry within the module allows the signal processing circuitry to be programmed with a desired frequency response or signal processing strategy using an external programming unit. A remote control unit permits the user to make simple adjustments, such as volume and/or tone (frequency) control.

    摘要: There is provided a method of supplying a fluid to a placement site. For instance, a sensor set is first mounted onto a skin of a user, and a placement site is contacted with the sensor set. The sensor set includes a base to secure the sensor set to the skin of the user; a cannula coupled to and extending from the base; an insertion device operatively coupled to the sensor set and the cannula to facilitate insertion of the cannula to contact the placement site; an externally extending conduit; and a sensor. The cannula has at least one lumen with an end for fluid communication with the placement site, and also has at least one port formed near another end of the lumen opposite the end for fluid communication. The conduit is in fluid communication with the at least one port of the cannula. The sensor has a sensor portion exposed by the at least one port in the at least one lumen of the cannula to determine a body characteristic of the user at the placement site. After the sensor set is mounted on the user's skin, a fluid is introduced through the externally extending conduit and the lumen to the placement site. Kits for carrying out the inventive methods are also provided.

    摘要: An implantable system, such as a neural stimulator or a cochlear implant system, includes a rechargeable battery configuration having improved recharging and lifetime characteristics. The battery is housed within the implant's case and has first and second electrode plates. Each electrode plate has a plurality of slits that extend across a substantial portion of the plate's surface area. The slits in the electrode plates reduce the magnitude of eddy currents induced in the plates by external ac magnetic fields allowing faster battery recharging times. Alternatively, the electrode plates are wrapped in a spiral configuration such that, in the plane of the spiral, the electrode plates have a small cross-sectional area and no closed current loops. Additionally, the implant device may be housed in a case formed of a high-resistivity material and a circuit included in the implant device is configured to avoid large current loops that would result in eddy current heating. As a backup option, the circuitry of the implant device may optionally be powered from an external battery that inductively couples energy to the same coil that is used to charge the internal battery. In one embodiment, the implantable system is partitioned into first and second implantable cases, each having electrical circuitry therein, and only one having a rechargeable power source therein, facilitating its subsequent replacement for repair or upgrading purposes. The two cases are coupled together when the system is in use. Coupling is achieved either magnetically and/or with a detachable electrical cable. In one embodiment, power is transferred from one implant case to the other using a 3-phase transmission scheme.

    摘要: A replaceable catheter system provides a way to replace an implantable sensor, electrode system, and/or fluid delivery/receiving system. The replaceable catheter system includes an implantable shunt, such as an arteriovenous shunt, attached to an implantable introducer. The introducer and implantable shunt are adapted for surgical implantation within a patient such that it extends from immediately below the patient's skin to the implantable shunt site. The replaceable catheter system further includes a replaceable catheter that is adapted to be contained within the introducer and properly aligned such that an implantable sensor, electrode system, and/or fluid delivery system that is carried by the replaceable catheter is placed in operative association with the implantable shunt and exposed to any fluids passing through the implantable shunt.

    摘要: An improved endocardial electrode (10) of the type having an electrical conductor (14) encased in material (16) which is generally inert to body fluids and terminating at an exposed, electrically conductive tip (12). A plurality of non-conductive, resilient tines (20) extends from the encasing material (16) near the electrode tip (12). Each tine (20) forms a substantially ninety degree angle with respect to the electrical conductor (14). A blocking surface (22) is provided adjacent to a portion of each tine (20) surface facing the electrode tip (12). The blocking surface (22) allows only an upper portion of each tine to be deformed in the direction of the electrode tip (12) while allowing the entire tine to be deformed away from the electrode tip, thereby providing a decreased deformation resistance as the electrode tip (12) is inserted into a vein (34) or between heart trabeculae, and an increased deformation resistance as the electrode tip (12) is withdrawn through a vein (34) or from heart trabeculae.

    摘要: A system is disclosed for controlling the charging of a rechargeable battery in an implanted human tissue stimulator by means of an external power source. Included in the stimulator are battery protection devices designed to sense the state of charge of the battery and limit the charging currrent amplitude so as not to exceed a selected maximum based on different criteria including battery state of charge signals from the implanted stimulator which are indicative of the current amplitude and battery state of charge from one of the protection devices are transmited to an external unit. Based on these signals the external unit is operated in one of a plurality of modes to cause the battery to be charged by a current with an optimum safe amplitude irrespective of determined failure of one or more of the battery protection devices.
